Senior Mechanical Engineer, Propulsion Systems and Integration
About The Position
Mach Industries is seeking a Propulsion Systems & Mechanical Integration Engineer to own the mechanical integration of propulsion systems across next-generation defense platforms. This hands-on role works across propulsion, structures, fluids, thermal management, avionics, and vehicle systems to turn propulsion concepts into reliable, testable, and manufacturable hardware. The engineer will integrate engines, fuel systems, valves, pumps, tanks, actuators, thermal protection, and related support hardware in tightly constrained aerospace vehicles. The role drives mechanical architecture and interfaces for propulsion systems while balancing performance, mass, packaging, manufacturability, reliability, and cost. The engineer will support prototyping and refinement of mechanical systems and optimize designs for performance and scalability, collaborating with a multidisciplinary team from concept through deployment.
Requirements
- At least 5 years of experience in mechanical, aerospace, or propulsion engineering, with significant experience developing and integrating complex mechanical systems in a fast-paced environment.
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related field.
- Strong skills in 3D modeling and CAD tools such as NX or SolidWorks for mechanical design and iteration, including GD&T per ASME Y14.5.
- Strong understanding of propulsion mechanical systems, including some combination of engines, fuel systems, tanks, pumps, valves, regulators, plumbing, mounts, and associated support hardware.
- Available to work extended hours and weekends as needed.
- Must meet the stated U.S. export-control eligibility requirements or be eligible to obtain required U.S. Department of State authorizations.
Nice To Haves
- Advanced degree (Master’s or Ph.D.) in Mechanical Engineering, Aerospace Engineering, Propulsion, or a related field.
- Experience with structural analysis, FEA, Thermal Desktop, or other analytical tools used to evaluate propulsion interfaces and hardware.
- Experience with programming languages such as Python, MATLAB, or C++ for analytical modeling, simulation, and engineering problem-solving.
- Direct experience designing or integrating engine mounts, fuel tanks, pressure vessels, fluid lines, valves, pumps, regulators, manifolds, and related hardware.
- Familiarity with slosh dynamics and mitigation systems, including baffles, foam, and bladders.
Responsibilities
- Own mechanical integration of propulsion systems from early architecture and concept development through prototype, test, qualification, and production.
- Develop and maintain propulsion mechanical interfaces for engines, tanks, pumps, valves, regulators, plumbing, actuators, mounts, supports, and vehicle structure.
- Define propulsion system packaging and installation architectures, balancing performance, mass, center of gravity, volume, thermal environment, accessibility, and manufacturability.
- Translate engine- and vehicle-level requirements into feed system requirements, interface documentation, and hardware.
- Perform first-order sizing and engineering analysis of mounts, brackets, plumbing supports, tanks, interfaces, and other propulsion hardware.
- Develop and manage propulsion mechanical interface requirements, interface control documents (ICDs), interface drawings, layouts, and configuration-controlled design data.
- Design and release mechanical hardware—including flight hardware, prototypes, test fixtures, and ground support equipment—using 3D CAD, drawings, GD&T, and appropriate engineering standards.
- Analyze and resolve propulsion-induced loads, vibration, thermal expansion, pressure loads, shock, and other dynamic environments at mechanical interfaces.
- Design and support installation, removal, servicing, inspection, and testing of propulsion systems.
- Support propulsion- and vehicle-level testing, including test planning, hardware readiness, instrumentation, anomaly resolution, and post-test assessment.
- Author technical documentation, test plans, interface documentation, trade studies, and engineering milestones for cross-functional and leadership review.
- Support critical development and test milestones, including occasional extended hours and weekends as needed.
Benefits
- Competitive compensation and performance-based incentives.
- Stock options or equity participation.
- Healthcare, dental, and vision plans.
- Retirement savings plans.
- Paid time off.
- Funding for continuing education, training, and career growth.
